The Red Sox designated Exposito and Michael Bowden for assignment in a recent roster shuffle. The 25-year-old Exposito spent last season at Triple-A, where he posted a .242/.298/.367 line in 359 plate appearances. He prevented one third of stolen base attempts from behind the plate.
Bell, once considered a top prospect, has fallen out of favor in Baltimore. He spent most of last season at Triple-A, where he posted a .253/.320/.438 line in 438 plate appearances as Norfolk's third baseman. He has a .485 OPS in 226 plate appearances at the MLB level.
